7045 Shift Cable Adjustment

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   How do,

I've (finally) got around to getting my 7045 going. This was one I purchased last year when the PO was going to scrap it due to hydraulic problems. The gear pump had sucked up some crapulence and one of the gears had cracked apart. I bought a new set of pump gears from Lynn on here (thanks very kindly Lynn!), polished up the bores, re-sealed what I could, cleaned the priority valve spool, and it seems to be functioning hunky-dory. Still want to check all standby and main pressures at all the relevant points to see if some tweaking is needed, but at least it's running/functioning and I'm able to drive it into the main shop.

Something about the shift linkage(s) feels awry: A little too much slop, you have to really max both range and gear levels out to the last 1/8" of their stroke to get into gear, a little stiff, etc. Same thing with the clutch - the adjustment for the second stage (transmission brake) needs some tweaking. I admittedly haven't even looked at these cables/linkages yet: I just got it going so I could get it moving, parked it in the shop, and went back to haying at the other farm. But I'm hoping to soon go over those cables/linkages and adjust them as needed. But I can't find anything in the operator's nor service manual about adjusting those cables/linkages. Maybe I just missed it in the manuals? Is there any specific method/tips for adjusting and setting those cables/linkages? Maybe it'll be obvious once I start looking at it?

Thought I'd ask before I make a special trip to that farm and then realize it's not self-evident.

	No way to know for sure but if youve got a lot if lost motion and they are stiff a new set of cables is probably in order

	It really does sound like OLD cables. Don't think book says. I start by trying to make new cable same length as old and install and go from there adjusting to get strokes evened out so travel is same like 2nd to 3rd from neutral. For me it's trial and error. New cables make a world of difference. I need to tweak my 8030 PD because it's not going into 2nd without over traveling from 4th or 5th. Thought it was correct when installed but field use says not. You won't have any trouble figuring it out. When done all gears should shift easily into respective slots. I've used Bunker Hill cables on 2 PD's and one PS. I think all the shift cables were plug and play but hyd control cables all needed a file drug across opposite sides to narrow the hsg to fit in slot. Have to pay attention to orientation of filing from one end to the other. Didn't want to widen holder incase ever went back to OEM.

	Thanks very kindly for the replies. Once I looked at the cables and pulled the floor from the cab I see you're right - it's pretty straight forward. In my case, the range shift cable was stiff - but is moving well now after using the old upside-down bag of oil and elastic band trick to let it soak through and lubricate the cable. And the gear shift cable braided sheath had broken right where the outer sheath goes into one of the crimped ends. I'll probably get a new cable, but for now I fixed it by splitting a small pipe nipple lengthwise, wrapping around the cable and stripping back a couple inches of the sheath, lightly welding one end of the nipple to the crimped end, and very carefully welding the other end (several tiny tacks) to the braided cable. Rather crude, but it seems to be working. Because I paid scrap price for this tractor and don't know what else might be wrong, I don't want to put too much money into it until I have more of a chance to put it through its paces. Next thing to fix is a problem of my own making: I was cleaning up the tools I was using in my tool trailer, and right there on top of the bench was a brand new Agco gasket: It a moment of formidable goofballery on my part, I put the pump in and forgot the gasket between the pump and transmission housing. So of course it has a slow drip and now I need to take it all off again to put the gasket in. Complete stupidity on my part. In my defence, I was totally rushing to get back together in the middle of the field where it was dropped. I was on babysitting duty, already angry and irked that I was losing haying time, driving around with baby babbling away and checking things out, and she fell asleep in the truck right as I was driving by the 7045. The tool trailer and parts were right there ready to go, so I thought I'd see how much I could get together before baby woke up. In the end I got it all back together that evening, but evidently I rushed a little too much. Next step after that is converting to open-station. Not sure if I'll cut down the cab or try and find fenders and make a new floor. Edited by DanielW - 14 Jul 2026 at 6:11pm

	Confused here. There isn't a gasket between the dual pump and the transmission housing. O rings seal dual pump into the housing. There is a gasket between the dual pump and the piston pump.

	Ah, you're entirely right Lynn - that's the gasket I forgot. Which makes me wonder why I have a slow leak at the pump-to-transmission mating. I definitely put new o-rings on, and I lubed them up and thought I was being exceptionally careful sliding the pump in the bore to not cut them. And a new seal on the input shaft of the pump too. Hmm - I'll have to look at it again tomorrow - only had one quick look in the dark once I noticed the gasket. Edited by DanielW - 14 Jul 2026 at 7:33pm
